Information 

• To unscrew the cardan shaft bolts, a second fitter should sit in the vehicle and block the drive train by actuating the foot brake. 
• The colour markings, match points -arrows- on the cardan shaft and on the all-wheel final drive flange must be aligned. This will neutralise the residual imbalance of the components. 
• Apply another colour marking if necessary.
